"Cristiano has pretty much everything. He can shoot with both feet. He can cross with both feet. His ability on the ball is exceptional. He can maneouvre the ball and generate space for himself," said Carrick. "We saw in the first leg how good he is in the air. You just have defend as best you can, work as a unit and help each other out.
"Both teams can attack well and we all have threats on the pitch that can create and score at any given time. That is the nature of the tie. Even though you might be defending well, you can never switch off - we had chances in the first leg and so did they. Either team could have won 2-1 or 3-1. It is who takes their chances on the night. We know we have to be at our very best to get a good result."
